寮步鎮機械密封利用(yong)機(ji)械(xie)方式傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在機(ji)械(xie)工(gong)程中應用(yong)非常廣泛，有(you)多種形式，主要包括皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿(gan)蝸(gua)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒輪(lun)齒條傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)螺(luo)旋傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。齒輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能夠用(yong)于大(da)功率的(de)場(chang)(chang)合(he)，傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比準(zhun)確(que)，但一般(ban)要求較(jiao)高(gao)的(de)制造精度和(he)安裝精度。還有(you)一類是靠機(ji)件間的(de)摩(mo)(mo)擦力(li)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)摩(mo)(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)摩(mo)(mo)擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。摩(mo)(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)容易實現無級變速，可(ke)以適應軸(zhou)間距較(jiao)大(da)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場(chang)(chang)合(he)，而(er)過載打滑還能起到緩沖和(he)保護傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)作用(yong)，但這種傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一般(ban)不能用(yong)于大(da)功率的(de)場(chang)(chang)合(he)，也不能保證準(zhun)確(que)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是寮步鎮機械密封的(de)更換工作大同小(xiao)異，首先拆前(qian)需確(que)認電機處(chu)于檢修狀態(tai)，擰下加油螺(luo)塞，用吸管把密封(feng)座腔內(nei)的(de)潤(run)滑(hua)油吸出。準備好放(fang)置泵零件的(de)工作臺及拆裝工具，切勿任意亂放(fang)亂用，避(bi)免碰壞泵的(de)零部件。

　　拆(chai)對分(fen)式聯軸(zhou)器(qi)：先把聯軸(zhou)器(qi)的固定內(nei)六角(jiao)螺(luo)釘擰下(xia)來，再(zai)輕輕把聯軸(zhou)器(qi)的一半(ban)從軸(zhou)上慢(man)慢(man)拉下(xia)，注(zhu)意(yi)不(bu)要(yao)掉了(le)，再(zai)用梅花(hua)扳手擰下(xia)泵軸(zhou)吊緊螺(luo)栓和擋塊，讓葉輪慢(man)慢(man)下(xia)沉(chen)至泵體，然后(hou)拆(chai)下(xia)另外一半(ban)聯軸(zhou)器(qi)，拿下(xia)泵軸(zhou)擋圈。

　　拆卸寮步鎮機械密封：抓住密封彈簧順著泵(beng)軸往上提，就能拆下(xia)來(lai)了。

　　拆(chai)卸并清洗(xi)軸承(cheng)(cheng)座：先輕輕松動(dong)一(yi)下(xia)軸承(cheng)(cheng)座后用(yong)(yong)拆(chai)卸螺(luo)栓頂起軸承(cheng)(cheng)座，并且沿著泵軸往上提而(er)卸下(xia)，再用(yong)(yong)噴(pen)氣燃(ran)料清洗(xi)軸承(cheng)(cheng)及座，裝前(qian)晾干并涂抹少許20號機械油用(yong)(yong)來潤滑(hua)保護(hu)。

　　拆密封座(zuo)：擰(ning)下密封座(zuo)壓緊螺母，輕(qing)輕(qing)卸(xie)下密封座(zuo)并清洗。

　　寮步鎮機械密封裝配(pei)：在動、靜(jing)環鏡面上涂一層潔凈的(de)20號潤滑(hua)油，導(dao)軸承座也抹上潤滑(hua)油，先把靜(jing)環輕(qing)(qing)輕(qing)(qing)定位(wei)(wei)裝入導(dao)軸承座，再在泵軸上抹上潤滑(hua)油，把動環部分(fen)輕(qing)(qing)輕(qing)(qing)裝入泵軸上，用(yong)手(shou)輕(qing)(qing)推密(mi)封環應能伸(shen)縮(suo)自如，注意動、靜(jing)環部分(fen)的(de)防轉(zhuan)部位(wei)(wei)需裝配(pei)到(dao)位(wei)(wei)。

　　裝聯(lian)軸(zhou)(zhou)(zhou)器(qi)：在(zai)電機軸(zhou)(zhou)(zhou)頭(tou)上裝上擋(dang)圈，裝上一半(ban)聯(lian)軸(zhou)(zhou)(zhou)器(qi)，再在(zai)泵(beng)軸(zhou)(zhou)(zhou)端(duan)和聯(lian)軸(zhou)(zhou)(zhou)器(qi)槽內裝上擋(dang)塊并用梅花扳手擰緊螺栓；再裝上另一半(ban)聯(lian)軸(zhou)(zhou)(zhou)器(qi)擰上內六角螺釘。安裝聯(lian)軸(zhou)(zhou)(zhou)器(qi)正確的檢(jian)查要(yao)求(qiu)：對分式聯(lian)軸(zhou)(zhou)(zhou)器(qi)上下間(jian)隙需要(yao)均勻，用手盤動聯(lian)軸(zhou)(zhou)(zhou)器(qi)幾圈檢(jian)查轉(zhuan)動的靈(ling)活(huo)性。

　　裝密(mi)(mi)封座(zuo)：先將密(mi)(mi)封座(zuo)裝入橡膠油封，再把密(mi)(mi)封座(zuo)裝入泵蓋(gai)并壓(ya)在軸承(cheng)座(zuo)上(shang)，擰緊螺(luo)(luo)母，確保所(suo)有安(an)裝螺(luo)(luo)釘(ding)緊固(gu)(gu)。當安(an)裝螺(luo)(luo)釘(ding)被用(yong)(yong)作(zuo)密(mi)(mi)封與(yu)軸之間(jian)的(de)(de)驅(qu)動時，軸應(ying)(ying)打(da)埋(mai)頭孔(kong)來加固(gu)(gu)連(lian)接，緊固(gu)(gu)壓(ya)蓋(gai)螺(luo)(luo)栓時應(ying)(ying)該平穩緊固(gu)(gu)，并且不(bu)要使(shi)壓(ya)蓋(gai)受彈力。在可能的(de)(de)地方使(shi)用(yong)(yong)4個以(yi)上(shang)螺(luo)(luo)釘(ding)的(de)(de)等間(jian)距壓(ya)蓋(gai)，緊固(gu)(gu)壓(ya)蓋(gai)螺(luo)(luo)栓時，用(yong)(yong)塞尺檢查軸與(yu)壓(ya)蓋(gai)之間(jian)的(de)(de)間(jian)隙，這在密(mi)(mi)封腔對壓(ya)蓋(gai)不(bu)導向時，顯得特別(bie)重要，因為壓(ya)蓋(gai)必須對中。
